Abstract:

To choose accurate and appropriate intraocular lens（IOL）is a major challenge of pediatric cataract surgery. Pediatric IOL power calculation suffers from significant prediction errors, which is caused by measurement errors and the IOL calculation formula errors. So it is very important to make a choice of measuring instruments and IOL calculation formula. Compared with the other formulas, the Holladay2 formula had the most accurate calculation outcome for the short axial children. Seven parameters (white to white cornea diameter, lens thickness, axial length, corneal refractive power, anterior chamber depth, preoperative refraction, age) will be measured for the Holladay2. To some extent, the formula achieves the personalized IOL power calculation, but the formula requires the children have enough cooperation. Along with the growth of the eyeball, the diopter of pediatric eye will change,  we should choose correct postoperative refractive target. (Int Rev Ophthalmol,  2017,  41:    110-115)
